Figure 1. Cumulative survival curves for four different gambling milestones representing.
(a) the age of gambling initiation in women versus men
(b) the time from gambling initiation until gambling at least once a week in women versus men
(c) the time from gambling initiation until the first symptom of disordered gambling in women versus men (among individuals whose time from gambling initiation to the first disordered gambling symptom was less than 18 years)
(d) the time from gambling initiation until the first onset of disordered gambling in women versus men.
Age was included as a covariate in all of the Cox proportional hazards models.
